Hi, I'm Hooi Teik ๐Ÿ‘‹

Software Engineering Managerโ€” 11+ years delivering cloud-native ecosystems across Azure, AWS & GCP.

About me

Software engineering leader based in Penang, Malaysia, with over eleven years of experience delivering cloud-native systems. Eight years at Seagate Technology culminated in a three-country manufacturing platform migration completed without scrapping a single wafer; three years at Motorola Solutions as Software Engineering Manager included more than doubling an engineering team, securing formal promotions for team members, and rebuilding Android build infrastructure on GCP for ten times the build capacity.

I have built with AI across both of its eras โ€” voice and NLP products before large language models, and agentic-AI engineering today. Everything on this site is built in public with AI as part of the toolchain: the Daily Architecture explainer series, and a property-search application that began as a hobby project and is now in daily use at home.

Things I've built

Global Build Infrastructure on GCP

Motorola Solutions ยท Cloud Infrastructure

Global engineering teams were constrained by legacy local build systems that limited concurrent build capacity.

Migrated the legacy build environment to GCP with on-demand scaling, as part of driving architectural standards and cloud cost optimization for global engineering operations.

๐ŸŽฏ Increased concurrent build capacity by 10ร— for engineering teams worldwide.

WAVE Apps Takeover & Expansion

Motorola Solutions ยท Mobile Radio Configuration

The WAVE configuration apps arrived as a US product transfer supporting only one radio model โ€” the TLK 25.

Took full ownership with the Penang team: enhanced the apps end to end and extended mobile onboarding and device synchronization across the remaining TLK models.

๐ŸŽฏ Coverage expanded across the TLK family, including the TLK 110 โ€” a product transition that grew the product rather than just maintaining it.

Monolith to Microservices

Seagate ยท Platform Redesign

A legacy US-based monolith limited scalability and made data consistency across features hard to guarantee.

Led the development pod decoupling the monolith into Golang and PostgreSQL microservices โ€” Saga pattern over NATS.io pub/sub for distributed transactions, a custom RBAC system modeled on AWS IAM, and automated CI/CD with Jenkins and Kubernetes.

๐ŸŽฏ Transitioned to a highly scalable microservices architecture and shipped the platform's complex subaccount model to production.
